Female remating, sperm competition and sexual selection in Drosophila.
This work examined female remating with respect to sperm competition and sexual selection in Drosophila and addressed the possible benefits for females, and reviewed the role of accessory gland fluid in remating.
Experimental Evidence for Nutrition Regulated Stress Resistance in Drosophila ananassae
Drosophila ananassae adapts different stress tolerance and life-history strategies according to the quality of the available diet, which are correlated with phenotypic adjustment at anatomical and physiological levels.
Fluctuating asymmetry in hybrids of sibling species, Drosophila ananassae and Drosophila pallidosa, is trait and sex specific.
The levels of FA of different morphological traits were similar in parental species and their hybrids of different generations in males (except SCTN) and in females (except for WL and W/T ratio).
Female remating in Drosophila: Comparison of duration of copulation between first and second matings in six species
It may be suggested that different species of Drosophila may vary in the incidence of remating and duration of copulation due to differences in their reproductive biology and adaptation.
Drosophila ananassae: A species characterized by several unusual genetic features
A heterojunction bipolar transistor (HBT) having an emitter structure capable of reducing the current crowding effect and preventing thermal instabilities is disclosed, wherein a negative
Effect of exposure to short-term heat stress on survival and fecundity in Drosophila ananassae
Heat pre-treatment improved survival of both male and female and also improved female pr...
Effect of Temperature on Longevity and Productivity in Drosophila Ananassae: Evidence for Adaptive Plasticity and Trade-Off Between Longevity and Productivity
It is found that females of Drosophila ananassae reared to adulthood at 18°C showed significant increase in body weight as compared to females reared at 25°C, and the usually close relationship between size and fecundity is lost when the size change is due to rearing temperature.

The work done on genetical, behavioural and evolutionary aspects in D. ananassae demonstrates that it is a ggod model species for such studies and enriched the understanding of basic phenomena like evolution and behaviour compared to similar studies on other model Drosophilds.
On the Combinations of Different Gene Arrangements in the Third Chromosome of Drosophila Ananassae
It has been suggested that natural selection which is main cause of maintaining non-random association of inversions, is not acting against recombinant arrangements in D. ananassae and it is unexpected in the light of results from other species of Drosophila.
